I finally got Vista mostly working with WebDAV authoring. The problem I'm having now is that Vista won't send the credentials that I specify to the WebDAV server. It always sends the local user's login and password which won't work on the server. I specified the correct login information during the setup of the connection, but whenever I restart it says that it couldn't reconnect because the user hasn't been authenticated. I patched the OS, added the server to the trust list in the registry, etc. Nothing gets Vista to send the alternate creds. When I change the local user / password the connection works fine. I'm close... and making WebDAV work has been SO frustrating. I could use any tips on getting this straightened out. Thanks!
